Abstract: A one-piece stripper retainer for plastic cup shaped strippers with a universal snap-in design that can be used with both older style and newer style punch retainers. The stripper retainer incorporates an anti-rotation heel with a snug fit around a portion of the punch retainer body and clamps to the punch itself. In a second version, the stripper retainer also clamps to the punch itself but lacks the heel. In a third version, the stripper retainer bolts to the punch retainer with a separate threaded screw. In all three versions, the plastic stripper is locked in place by the snap-in feature without any additional clamping force.

Abstract: A technique for forming and mounting a handle which includes the steps of providing a channel-shaped body of metal with opposed flat lugs at its midportion, inserting a metal rod perpendicularly into the channel-shaped body in tangential surface contact with the inside surfaces of the lugs and in abutment with the inside wall surface or web of the body, mounting these interengaging parts horizontally in a holding jig provided adjacent the stationary lower electrode of an electric welder with the bottom lug engaged on the electrode, and lowering the other welding electrode into contact with the upper lug, so as to weld the lugs to the opposite sides of the rod at the tangential contact surfaces.
